Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Smartpilot View group
General anaesthesia managed by the Smartpilot® View device The intervention consists of administering hypnotics and opioids according to effect-site concentrations and interaction model provided by the Smartpilot® View software for the entire duration of general anaesthesia.

Active Comparator: Control group
General anaesthesia without using the Smartpilot® View device The anesthetic induction will be performed by propofol or sufentanil and atracurium. The maintenance of anesthesia will be directed by desflurane and sufentanil. The dosages of anesthetics are left to the discretion of the doctor and nurse anesthetists in charge of the patient in the operating room.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of time spent in the "appropriate anaesthesia zone"
Time Frame: participants will be followed for the duration anesthesia, an expected average of 5 hours (from intubation to recovery) for hip fracture surgery
The "appropriate anaesthesia zone" is defined as a bispectral index between 45 and 65 and a systolic blood pressure between 80 and 140 mmHg
participants will be followed for the duration anesthesia, an expected average of 5 hours (from intubation to recovery) for hip fracture surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Dose of propofol
Time Frame: participants will be followed for the duration anesthesia, an expected average of 5 hours
participants will be followed for the duration anesthesia, an expected average of 5 hours
Dose of sufentanil
Time Frame: participants will be followed for the duration anesthesia, an expected average of 5 hours
participants will be followed for the duration anesthesia, an expected average of 5 hours
